Some Inside Facts On 'Back To Future'

HOLLYWOOD — Though Universal Pictures and producer Steven Spielberg have been hush- hush about Back to the Future, opening in July, some detective work has uncovered the following:

Michael J. Fox plays a student who performs in a rock band and hangs out with scientist Christopher Lloyd, whose nuclear-generated, time-traveling Delorean zaps Fox back to 1955, the year his parents met as teen-agers.

But the arrival of Fox fouls up fate -- his folks do not meet and fall in love as they're supposed to. Fox gets to teach the kids of 1955 about things like rock 'n' roll and skateboards. He also has to figure out how to get back to the future.
